ABSTRACT:
A variable camshaft assembly which serves to vary the timing of poppet valves in an internal combustion engine. An axially movable wormed camshaft controls a number of splitable cams of conventional cross section operating individual valves. When the camshaft is shifted axially, each valve operating cam splits into two operating elements. When the raised noses of the splitable cam elements are in alignment, the valve event is minimal. When the raised noses are in misalignment, the valve event is extended.
